` in the perfection of a structure. the various parts of which are so related that the contailler, which is prcfcrnhly mode of glass, will lnot be broken and further, container will he relieved of e hreoking jjar should thc' extinguisher ns e whole roughly handled or dropped. i

MyV structure is also arrsnged so that there are no parts which project bevond the sides of the extinguisl'ier use 1.rhole to rcduce the likelihood of its becoming caught while being transported. Further. the projections will not heeomc broken no easily lwhen thus located out of (longer, for they cannot be engaged duringr n. fell or hump to inturn transfer the shock to the container.

" Another object of my invention resides 1n f `fha wmbination'of an individual or 'unitary 'container and its surrounding protector Casing, with u Slottvld Sight oponh|g"'ui1fl n pressure gage, whereby the emou nt of extinguishingchemical and the eren of compressionchamber muy he readily discernml when the sight gage is read in cormoction with 'tlvpressure'gage. This arrangement is esser tial, first, for the reason that n. given vohnnc of?, compression s|1uice is necessary' 1o n'rsure,`

the etpclling of `all of `the extinguishing rhcxnutl and, therefore, the two lluuls muy hc' so proportioned that, when rend 1n con- -`4,5` Neotion with the two galgos, en adequate amount f one muy' he supplied as required by theother. The slotted sight gage when windl in connection V1with the interior chemii nelV contulneniand protectm-'cnsing "rsrrelso essentiah in that vit relieves the expelling present-ein case the container'shouldhe broken `without.,4 shattering the protector casing. ln' thisl wey, the cxtinguisher'is Y tendered perfectl safe to handle for, should the chemical container. be broken for some that this 4-4 of Figli, and,

reason or other, the parts of the extinguisher will not he shattered and thrown into the surrounding space because of the internal pressure, for the reason thatthis pressure is relieved h v escaping into the surrounding space through the slotted sight gage. i

S ll1 a further object of my invention re sides in an arrangement of check "alve structure whereby the check valve is held open against the internal pressure `of the rontainer s the fluid is heine: discharged and when the container is held in its proper position. However, should the container be in vcrted, the structure is such tht the check valve will automaticallyclose the passage lending through the nozzle. I have resorted to this type of arrangement for the` reason that it is more difficult to confine air or gas than it is a, liquid, and also to prevent re 75 lease of the air or gas should the valve be opened `when the extinguisher is in en inverted position which would release the lliq uid expelling pressure. The arrangement is such that normally, the lquid is in contact withlthe discharge poi-'nts and. therefore, the reduction of pressure isl'css likely than were the invcrf;e`truc, for, it 4is easier to pack n joint to make it 'impervious to liquid than f it is to gos or nir, but, because of this check 86 valve structure, no mutter in which4 position the extinguisher may be, opening of the nozzle vulve muses tln.A outflow of the liquido r nothin The preferred enihodiment of my inven- 90 tion is shown in the. accompanying sheetpfdruu'ings, in which similar characters o rc'forcmze designate correspondinglparts, und in which:

4the extreme end ofthe neck or, in other words, the mouth portion is provided with an annular exterior shoulder shown at 3 for a' purpose to be presently described. This container is surrounded by a'metallic casing 4 provided with longitudinal slots 5 atA diametrically opposite points by means of which the flu d level may be readily observed and this container is securely packed 3 are designed to projecting hollow position v position,'tlie -nut 11 is turned to draw the within the metal shell by means of the packing shown at 6. To enable the entire extinguisher to be readily transported, I have provided the top portion with the handle 7. The lower end of the shell is flaredto present a' base 8 of approximately the same diameter asthe shell, upon which therextinguisher as a wholemay be supported. To the lower end or to the mouth of thebot'tle, there isattached a he is designated generally by the reference numerel 9,' the uppenportionof this head being rovided with a channelto 'receive a suite )le packing 10 and one legbf this'channel is threaded to form the means of attachment of a nut 11. This nut isfurther r0- vided with an inwardly extending shou der 12 which shoulder 12 and the glass shoulder coperate wlth a plurality ortion which '0f 'flllalely Shaped retaining wires 13th means *of which the head are detachably connected. These-retaining wires *are made in arcuate sectionsin order that they may be inserted V'totheiroperat'ive and after they have au'med such and the bott e parts securely to ther against the ackin 10.` This head ieg-provided with a-lgterallg vstem 14 ontolthe outer en of which a pressure inspection -of`Fig- 3 will disclose that this gage is, therefore, at all times in communication with the interior of"X the bottle to give a' visual indication of.; the pressure within. ...This portion of the head 9 is held in` with the` base8 bylvriewing a semi-rigid oonnection suiiciently yielding,r to act as a cushion effective'when the extinguisher is given a jar or fall. Thus if the upper end of the bottle should bemoved slightly by av fall,

as. opposed to metal, in that the extinguishgage 15 is Sured. An

:this air then come th .rfld 'by-athe outerfend-of zth stom '14@ 'dofwn `1 onto` a of; the.` .Shape Shown fstructurefis used at this and where projections carried 'hythehead 9pm through the -shellto give peines-than rit would open position against f when in Fig. 1bu't which `will automatically closeA the head is permitted to also shift slightly by compressing portions of the cork washers, whereas vif this head were rigid with the shell, any tendency to move the upper end of the bottle would place all the strain on the bottle neck. This arrangement is also very convenient when assembling the extinguisher. This head 9 with the passa' way passageway lea s to a point to communicate with the discharge nozzle shown at 19. This nozzle is threaded practicallythroughout its entire length, the rear portion of it being threaded into the head 9 as is shown and the forward portion receiving the nut 2O by means of which the cork washer 21 may be compressed against the base 48 in a manner similar tothat described in connection with the gage member. The cxtreme cuter end of the nozzle 19 is also threaded as is shown at 22 in order to readily secure a connection with a tire inflating mechanism in recharg- 'ing' the extinguisher as will be presently related. Thecommunica-tion of.the nozzle with the interior of the container, is controlled bv means ofy the valve shown at 28 which valve packed in connection with the base 8 in the same manner as has been describedfor the nozzlel and gage member. Release of the valve 23 will permit the Huid to 4enter thel vertical passage shown at 26 in Fig. 4, then around the valve. through vthe and outthrmigh the nozzle 19.

It will be observed `that the container 1 is -in an Vinverted position so that its discharge passage 18 is further provided i shown at 18, which opening is 'at the bottom when in its--opera- 1 tive position in which mannerthe vextinguishing fluid is maintained in contactwith the controlling valve and gage structure and in which position 'the expelling pressure gas cannot possibly' escape by 'opening o f the valve 23 since it is the space above the fluid level'which-is filled with fair compressed` to high 'degree and upon'k release of the valve, e discharge of the fluid out through, the1 nozzle' as-has'been reg lated. Itis 'much-'easier 'to control or con-y eontainer when this,

fine the vvliquid to liquid Tis in contact with the discharging ether-gemeend; therefore; I have varranged guard' against misuse, Tv have provided a 'supplemental valve structure .or a check valve structure arranged to remain in an E the internal pressure the-container is' in the position shown beto onkne'the air or "thews'tru'cture'so thatits normal position is 'also'. its operative-position. However. to

isty

the outlet passage whenthe container is moved to an inverted position, in which case the compressed air will, be in contact with `the discharge parts and `vsg'll not escape iShould the release valve be opened. This check valfvestructure comprises an ordinary tapered valve such as in shown vat 27, the underside of which is provided with a guide rod 28 to guide the valve in its vertical movement. The lower side' of the valve 27 is formed integrally with an L-shaped rod 29 and the upper end of this rod is pivotally connected at 30 .with the wei tarm 31. This weight arm 31 is in turn plvota'lly mounted at 3'2 in connection with a supporting stand-- ard 33 and the weight :i4- on the end of this rod when considered in connection with the dilierence in leverage between it and the pivot connection 30. will hold the valve 27 away from its seat after the discharging valve has been opened and against the internal pressure. However, when theextinguisher as a` whole is inverted, this weight acts in a` manner to automatically close `the check valvegno matter whether there is l.

slight leakage at thin point or not. Further,`

an)T liquid confined in the passage 26 will then be held confined by the check valve to `further seal a possible source obeooape of the gas. I have provided the gage member 15 so that it ma)v readily be determined whether the internal pressure has been' reduced through leakage or not.

After the liquid within the container has been discharged the same 'may be recharged by removing the plug 35 Secured in thc lower end of the head 9 and filling the container to the desired lepel. After this, the plug is replaced and securely wedged against the gasket Bti. The extinguisher as a whole is then inverted and the threaded portion 22 of the nozzle attached to a tire pump or air compressor of some The valve 23 is then opened and compressed air introduced into the container until the gage 15 shows the proper pressure, whereupon the valve 23 slclosed and the extinguisher again righted to bring the liquid into contact with thedischarging parts as hae been previously related. l
